UNITED STATES PATENT OFFICEQ LEON O. GORELL, F KALAMAZOO, MICHIGAN,ASSIGNQR OF ONE-THIRD T0 I-IIRAM D.

SWAYZE, OF KALAMAZOO, IJIICHIGAN.

moon To all whom it may concern:

Be it known that I, LEON O. CORELL, a citizen of the United States,residing at Kalamazoo, Michigan, have invented certain new and usefulImprovements in Tools, of which the following is a specification.

This invention relates to improvements in tools. a

My improved tool is especially designed by me for use in stringing orplacing electric circuit wires.

The main objects of this invention are: First, to provide an improvedtool which facilitates the placing or stringing of electric circuitwires. Second, to provide an improved tool having these advantages whichmay also be readily adapted as an adjustable boring machine or tool.Third, to provide an improved tool for use in wiring, which is simple instructure and operation and very convenient to use.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Figure I is a side elevation of a structure embodying the features of myinvention, the driving chain being omitted, and a part of the shaftbroken away, it being shown with the chuck 5 in the holder socket. Fig.II is a side elevation looking from the right of Fig. I, the adjustmentof the holder member 3 beingindicated by dotted lines. Fig. III isadetail side elevation partially in vertical section, with the chuck 5removed, and an insulating knob or wire support and wire in the holder.Fig. IV is a detail view partially in longitudinal section, on a linecorresponding to line 4-i of Fig. II. Fig. V is a detail elevation ofthe chuck 5; Fig.

In the drawing, similar reference charac- "ters refer to similar, partsthroughoutthe several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawings, the shaft 1 is provided with arms 2 at itsupper end. The shaft is, in practice, adjustable so that the piperatormay support the tool from the cor. shaft form no part of my presentinvention, I have not illustrated the same herein. The holder member 3is provided with a socket l adapted to receive a wire support orinsulating knob, as shown in'Fig. III, or a chuck 5, as shown in Figs.I, II and IV. Theinsulating knob or wire support shown, consists of thebase portion 6 and cap portion 7, which are grooved at 8 to receive awire, as

The holder member is slotted at 11 to receive the wire9 so that the wire is arranged in the grooves The holder member can Asthe adjustment features of the and the screw inserted through thesupport, :1

and thus assembled, the parts drop into the holder. See Fig. III.

To assist in supportlng the wire and renderit more easy-to draw tightwith the parts assembled and in position to be attached, the

holder is provided with laterally projecting grooved arms 12 alined withthe slots 11. The arms 12 are provided with a supporting ring 18 whichis sleeved over the holder, "as

shown, the sleeve resting upon the shoulder 1%, and being retained onthe holder by the chuck retaining screw 15, the chuck being providedwith an annular groove 16 into which this screw projects. See Figs. IVand V.

The holder is carried by the support member 17 having laterallyprojecting ams 18 disposed between the arms 2 of the shaft. The member17 is adjustably supported by the screws 19 arranged through the arms 2.One of the arms 18 is adapted as a bearing for the driving gear 20. Thisdriving gear is arranged in mesh with the driving gear 21 on the end ofthe spindle 22. The spindle 22 is provided with a screw driver blade 23adapted to engage the screw 10, as shown in Fig. III. The spindle isprovided with pin-like driving members 24: adapted to engage jaws formedby slots 25 in the chuck so that when the chuck is inserted in thesocket it is in driving engagement with the spindle. The chuck ischambered at 26 to receive the screw driver blade. In Figs. I, II andIV, I have shown the chuck with a screw driver 27 secured therein. Itwill be understood that any desired tool may be arranged in the chuck,and in Fig. VI, I illustrate a bit 28 designed to fit the chuck. Thedriving gear is provided with adriving sprocket 29 for the driving chain30. Further details of the driving means are not illustrated as theywill be readilyunderstood.

My improved tool is adapted for boring or for other work, and isadjustable so as to be operated in various positions, as on ceilings,side walls, corners, between studding or the like, and may be operatedmainly from the floor so that the work is rendered easier and may bemore rapidly performed.

I have illustrated and described my improvements in a simple andpractical embodiment in which I have used the same.

While I am aware that various modifications are possible, I have notattempted to illustrate or describe such modifications as I believe thedisclosure made will enable those skilled in the art, to embody myinventions as conditions or circumstances may dictate, and I desire tobe understood as claiming my improvements specifically in the formillustrated as well as broadly within the scope of the appended claims.

Having thus described my invention what I claim is new and desire tosecure by Letters Patent is:
